UCLA measles quarantine greatly reduced

A measles quarantine at the University of California, Los Angeles, has been greatly reduced.

Spokesman Tod Tamberg says one student is still quarantined on campus today. He says fewer than 50 students and faculty members have isolated themselves at their houses off campus while officials determine if they've been vaccinated or have immunity.

The school was notified Monday that a student with a confirmed case of measles had been on campus this month. Initially, more than 500 students, staff and faculty were notified they may have been exposed.

Most were cleared, and public health officials quarantined 127 people Wednesday. That number was rapidly reduced as people established proof of immunity.

Possible measles exposure forced California State University, Los Angeles, to send home 198 staffers and student employees of a library this week. An update isn't expected until later today.
